I have installed squeeze on a HP notebook. I have one small problem though.It does not resume from suspend. If I shutdown -> suspend, or close the the lid, or shut downs (suspends) as expected, but when I then power it backup up, the screen just stays black.

I had this same problem in Squeeze (not Lenny) on an Acer Aspire 5102WLMi. I disabled KMS and the problem disappeared. To disable KMS for an ATI card like yours and mine, you simply edit /etc/modprobe.d/radeon-kms.conf. There is only one line in the file. Change it from a 1 to a 0 (zero), save the file, and reboot. Also make sure that you have the "firmware-linux-nonfree" package installed. My ATI card required it, though yours is higher-end than mine.

I have the same problem on my old laptop with the i915 driver. If I close the lid it freezes. The fact that the latest intel driver requires KMS in order for xorg to work at all doesn't help either. It was freezing at the point where it changes to the framebuffer console using the stock squeeze 2.6.32 kernel and only works ok with a 2.6.35 or higher kernel.

It should all be success or not applicable. Anything else would be a good starting point for inquiry.

Next is to start reproducing using pm-suspend from terminal as root and supplying various quirks. Open-suse had some of the best documentation on the quirks that I recall coming across. Once you find a quirk that works you can edit /usr/lib/pm-utils/sleep.d/quirksfile to match.

If you switch to a VT1 then back to X and the video comes up, there's a quirk for that.

Not the official driver. I was told all I needed to do was install "firmware-linux-nonfree" and it would work. It does, and quite well too. The card is an ATI1100M, not a high-end card. Would I see any benefit (increased FPS) by switching to fglrx?
